Difference lies in the area, manufacturing cost, and safety coefficient. Below is the relevant introduction: Car sunroof: A car sunroof is installed on the roof, which can effectively circulate air inside the car, increase the intake of fresh air, and also meet the needs of expanding the field of vision and mobile photography. Built-in sunroof: A built-in sunroof refers to a sunroof where the sliding assembly is placed between the interior and the roof. Its advantage is the large opening of the sunroof and a simple and beautiful appearance. Most sedans use built-in sunroofs. However, if it is an add-on, the price of this built-in sunroof is relatively high, and because the roof interior needs to be redone, the required construction technology is also very high.

I've been driving for almost ten years, and the most noticeable differences between a panoramic sunroof and a single sunroof are in visibility and practicality. The panoramic sunroof covers most of the roof area, allowing you to look up and see the entire sky while sitting in the car. It feels especially amazing when cruising in the suburbs, with ample natural light, and the kids in the back seat don’t feel stuffy. A single sunroof, on the other hand, is just a small opening, covering at most the area above the front seats. It provides decent ventilation but has limited visibility and poorer lighting. However, panoramic sunroofs also have significant drawbacks—they usually can’t open fully, only a crack, and cleaning them is a hassle. The large glass area tends to accumulate dust and requires frequent maintenance. They’re also heavier, which affects fuel efficiency. In terms of cost, panoramic sunroofs are much more expensive and complicated to install. For daily commuting in the city, I prefer the practicality of a single sunroof; but for trips, the panoramic one really adds value, creating a fantastic atmosphere.

As a car enthusiast, I have some understanding of sunroof construction. Panoramic sunroofs use large-area tempered glass, offering an expansive visual effect and enhancing the sense of space inside the car, but the roof strength needs reinforcement to prevent accidents; single sunroofs mostly consist of metal frames with small glass panels, featuring a lightweight and simple structure. Functionally, panoramic sunroofs provide UV protection and heat insulation, offering good sun protection in summer but poorer ventilation, as most models only allow partial sliding or fixed opening; single sunroofs can be fully opened for faster ventilation. There's a significant cost difference, with panoramic sunroofs being several thousand dollars more expensive and maintenance being more cumbersome. In terms of safety, panoramic glass poses higher risks if shattered. I've used both types—panoramic sunroofs are enjoyable on long trips, but single sunroofs are more worry-free and energy-efficient in the city. The choice depends on personal preference and budget.

With kids in my family, the panoramic sunroof makes the car more comfortable and well-ventilated for everyone, especially on highways where children don't cry and find the sky view fascinating. However, its large size makes it difficult to clean and expensive to maintain, with a slight risk of leakage. A single sunroof is smaller, easier to maintain, practical, and safer.
